IMPROVEMENT IN COMBINED BAG-HOLDER AND ELEVATOR..

Specification forming part of Letters Patent No. 38,183, dated April 14,lb.

To all whom it may concern:

Be it known that I, GEORGE H. SMITH, of Des Moines, in the county ofPolk and State of Iowa, have invented a new and Improved Elevator; and Ido hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accomi panyin gdrawings, forming a part of this specification, in Which- Figure 1represents a longitudinal vertical section of my invention, taken in theplane indicated by the line m w, Fig. 2. Fig. 2 is a front elevation ofthe same.

Similar letters of reference in both views inv dicate correspondingparts.

The principal object of this invention is to enable the laborer to llgrain-bags without assistance and to elevate the same to a convenientheight from the iioor to load them onto his shoulder without having tostoop over or require other help.

The invention consists in the arrangement of a movable frame containinga rising and falling platform secured to a sliding rod, from which, at aconvenient height, two curved arms extend, which are provided with hooksto attach a bag for filling the same, in combination with a windlass,zatchet, and pawl in such a manner that a bag, on being suspended fromthe hooks on the curved arms can be convenient-ly iilled, and when full'the platform can be readily raised by means of the windlass, andretained at a convenient height by the ratchet and pawl, thus enablingone man to ll the bags and lift them onto his shoulder without anyassistance, the whole being so arranged that it can be convenientlymoved from one place to another and put up wherever the elevator is tobe used.

To enable others skilled in the art to make and use my invention, I willproceed to describe it with reference to the drawings.

A represents a frame, made of timber or other suitable material, and ofsuliicient strength and height for the occasion. This frame is providedwith a vertical guideway, a, formed by two strips, b, which are securedto the lower and upper cross-timbers of the frame A, and said way formsthe guide for rising and falling bar B, to which the platform O issecured. This platform", is steadied by two curved rods, c, in front,and by rods d in the rear, and all those rods are fastened to across-bar, e, which is rigidly attached to the rising and falling bar Bat a convenient distance above the platform.

D are two curved arms, which connect in the middle, being firmly securedto the rising and falling bar B. A slot, f, in said bar allows ofadjusting the curved arms higher or lower, as may be desirable. Thesearms are provided with hooks g, which are in such a position that anordinary grain-bag can be conveniently suspended from the same for thepurpose of lling it. The rising and falling bar B is suspended from arope, h, which is secured with one end to a staple, i', inserted intoone of the upper cross-timbers of the frame A, and which extends under apulley or she-ave, j, and over another sheave, k, its other end beingmade fast to a stud or staple, l, projecting from the circumference of awindlass, E. The sheave j has its bearings in a block, j', secured tothe rear surface of the rising and falling bar B, and the sheave la isfastened in a block, lc, suspended from the top of the frame A. Thewindlass is arranged on the rear of the frame A, and it has its bearingsin suitable journalboxes secured to two of the uprights of said frame.It is operated by means ot' a winch, m, and a ratchet-wheel, n, and pawlo enables the operator to raise the platform to any convenient heightand arrest the windlass without other assistance. .A hook, F, secured inthe top of the frame A, is intended to support a steelyard or scales forthe purpose of ascertaining the weight of each bag after the same hasbeen filled. By this arrangement a bag can be filled without assistanceby suspending it from the hooks on the curved arms, which are adjustableto a convenient height, according to the size of the bag, and whenfilled each bag can be readily elevated to a convenient height to allowthe laborer to load it onto his shoulder without stooping down.

I do not claim as my invention thev rising and falling platform in themovable frame, neither do I claim the windlass, nor the ratchet- Wheeland pawl; but,

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The combination of the adjustable arms D and hooks g with the movableframe A, rising and falling platform C, rope la, windlass E,ratchet-wheel a, and pawl o, all constructed and operating in the mannerand for the purpose setforth.
